konaworld For 2014, you'll find the simplicity, strength, comfort, resilience and playfulness of Kona Cromoly interspersed throughout our road- and mountain-bike platforms. Very few materials offer as much shock absorption, durability and supple-ride characteristics as steel. We’ve never strayed from cycling’s original material and have worked tirelessly to adapt, refine and innovate Cromoly framesets as rider demands continue to evolve. Short chainstays and seatstays provide a perfect balance of stability and power transfer when out of the saddle and pedaling hard. Shorter seatstays also have less deflection during braking and accelerate faster than longer stays. Kona warrants to the original owner that their new Kona bicycle frame purchased from an authorized Kona dealer shall be free of defective materials or workmanship for the lifetime of ownership by the original owner.

Ultra-efficient 4,000 mph vacuum-tube trains – why aren't they being built? In the 1800s, when pneumatic tubes shot telegrams and small items all around buildings and sometimes small cities, the future of mass transit seemed clear: we'd be firing people around through these sealed tubes at high speeds. And it turns out we've got the technology to do that today – mag-lev rail lines remove all rolling friction from the energy equation for a train, and accelerating them through a vacuum tunnel can eliminate wind resistance to the point where it's theoretically possible to reach blistering speeds over 4,000 mph (6,437 km/h) using a fraction of the energy an airliner uses – and recapturing a lot of that energy upon deceleration. Ultra-fast, high efficiency ground transport is technologically within reach – so why isn't anybody building it? The next frontier of speed Vacuum tube-based transport has a lot of things going for it. The vacuum-tube revolutionaries The case for the negative Then again, let's say these safety issues can be adequately addressed.

CB550 Custom Build by S&G builder Brady Young - Seaweed & Gravel Custom build by Seaweed and Gravel in southern california built by Brady Young (previously of UGLY Motorbikes.) The inspiration for this build was spawned from a previous personal bike of Brady's, made from spare parts and a few weekends. The bike was rough, full of character, and frequently saw the dirt. Nonetheless, it caught the eye of the client that commissioned this build, but with new shoes and a classy attire. Our goal for this build was to create a simple, clean, minimalistic bike with an aggressive, low stance; pulling elements from both the cafe racer and brat style palettes, whilst preserving the classic lines that were buried in stock form. The top end was rebuilt with new internals and tuned by a retired racer and mechanic of the time, making it a true one kick cold started. Our theory on the finish of our bikes is overall modesty with bold features.

Nanotech versus the pirates: Zyvex Marine unveils the LRV-17 Zyvex Marine's latest nanotech-enabled lightweight boat, the LRV-17 Image Gallery (5 images) The purveyors of fine nanotech-enabled lightweight boats at Zyvex Technologies have been in touch to tell Gizmag about their latest creation, the LRV-17, developed to combat piracy off the coast of Africa. At 17.35 m (57 ft), the LRV-17 is a slightly bigger boat than Zyvex's unmanned Piranha USV, but unlike its piscine predecessor the LRV-17 can support of a crew of six for up to five days. View all Like the Piranha, the LRV-17 is made from "carbon fiber nanocomposites," Arovex and Epovex, which are crucial in keeping the boat's weight down to 17,900 pounds (8100 kg). The result is a vessel 17.35 m (57 ft) long, 3.6 m (11.9 ft) wide boat with a 0.75 m (2.3 ft) draft - that's the vertical height from water level down to the hull's bottom.

Roberts Cycles - handbuilt lightweight custom bicycles and frames Prends ton vélo 2013 First manned flight of FanWing aircraft planned for next year The FanWing company has announced that it plans to debut a piloted version of its rotary fan-powered aircraft next year Image Gallery (11 images) With a traditional airplane, a propellor or jet engine pulls it forward, and lift is created as air subsequently flows over the wings. FanWing aircraft are a little different. They have a powered horizontal rotary fan along the leading edge of their single wing, which serves to pull air over it, creating lift without the need for speed. View all First of all, why would anyone want to build an airplane this way? According to the company, due to the fact that little in the way of speed is required to achieve lift, FanWings can take off and land on very short runways. The piloted aircraft is planned to have a rotor measuring 32 feet (10 meters) long by 30 inches (75 cm) wide, with a total body span (including its twin tails) of 46 feet (14 meters).
